T FFTFW VERTIOALLY-ADJUSTABLE SHADE-HANGER.

Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed July 10, 1914. Serial No. 850,166.

To all whom it may concern: H

Be it known that 1, WILLIAM J. BRITTING, a citizen of the United States, residing at Washington, in'the District of Columbia, have invented certain new and useful Improvements in Vertically-Adjustable Shade- Hangers, of which the following is a specification.

This invention relates to shade hangers and more specifically to vertically-adjustable shade hangers.

The object of my invention is to provide a vertically adjustable shade hanger which will be simple in construction, durable, and efiicient in operation.

An entirely new method of sliding adjustment is provided by means of the adoption of a ball-bearing slide, whereby the sticking tendency of adjustable shade hang-, ers experienced with practically all other constructions, is entirely overcome. 'It is this tendency to stick which causes the shade, in other constructions, to get out of horizontal alinement and thus become inoperative. By my ball-bearing arrangement, the sliding is absolutely certain and sticking or catching'impossible.

Furthermore, my invention also embodies a guide for the end of the shade, whereby the same is maintained in horizontal alinement, prevents the shade from rolling up unevenly, and also acts as a stop so that the shade will not wind up on the roller until the spring force is exhausted as so frequently happens with shade hangers as at present constructed.

Other objects of this invention not at this time more particularly enumerated, will be clearly understood from the detailed description and drawings forming a part-of this specification.

Furthermore, this invention consists in the novel arrangement and combination of parts more particularly described in the following specification and embodied in the claims appended hereunto and forming a part of this application.

Referring now to the drawings which are merely illustrative of my invention, Figure l is a front elevation of my vertically-adjustable shade hanger in operative position upon a window. Fig. 2 is a cross-sectional view of one of the shade carriers taken on the line 2-2 of. Fig. 1, while Fig. 3 1s a front elevation of the opposite carrier Show ing the operative position of the ball-bearings. Fig. 4 is a perspective of the pulley through which the adjustment cord passes. Fig. 5 is a cross-sectional view of shade guide and stop device taken on the line 55 of Fig. 1, while Fig. 6 is a detail perspective ofthe guide and stop member.

Referring further to the drawings, wherein similar reference characters indicate similar parts throughout the respective views, 1 designates a window casing, upon both sides of which is vertically mounted a guide member 2, best described as a rectangular sheetmetal tube, provided with a slot 8 along the longitudinal center through the outer face thereof. Shade hanger members 4 are adapted to be slidably mounted within said slot 3 and to be held in engagement in said tubular guide by means of ball-bearings 5 set into perforations 6 through said hangers near the bottom thereof. Said bearings are arranged on both sides of said hangers in staggered relation to each other. The said perforations are in the form of a concavity and are of a diameter to receive so much of the balls only as will admit of contact by the balance of the ball with the side, top and bottom of the tubular guide member, thereby insuring perfect stability of the hanger as well as smooth and easy running of the hangers to any position in the guides.

When it is desired to secure the guide members 2 to the front of a window casing fastening means are inserted through the bottom of said guide members, but when it is desired to secure them to the sides of a window casing a 2-shaped metal band 7 is clamped upon the outer portion of said guide member as shown in Fig. 5, and the free end thereof is secured upon the casing at 8'by suitable fastening means.

The shade '18 is forced to roll up in vertical alinement by means of angle-iron slide members 9 secured upon both sides of the slat 19 at the end of the shade. The said slide member 9 is formed of a piece of sheet metal with one endthereof bent downwardly at right angles to portion 9 thereof, thus forming a foot portion 11 centrally disposed with respect to two lugs 12 which project outwardly from said foot portion and at right angles thereto, said lugs being formed thereon at a certain point below the plane of portion 9 and above theterminal point of foot 11. In operative position, said foot portion 11 rests upon the bottomiof guide 2, while lugs 12 fit within the guide and slidably engage with the top thereof, being adapted to retain the slide within guide member 2 and also serving as a stop, when the curtain is rolled up, by reason of the contact of the lugs 12 with hangers 4. Portion'9 of said slide member-is provided with a longitudinal slot 10 therethrough, for ready adjustment upon the slat 19 so as to fit into the guide members 2; fastening means being inserted through said slot.

011 bothsides near the top of the window frame 1 and adjacent the upper ends of each of the guides 2 is -mounted a pulley 13. The wheel .13 of said pulley 13 is inclosed on two sides 13 and '13 and one end 13 thereof by a sheet-metal piece folded to so inclose said-wheel; the opposite end being partially inclosed by means of oppositely-arranged lugs 1% extending from the side 13 to a certain point short of contact with the other side 13. This form of pulley is essential in order that the adjustment cord 15 may be readily inserted between the ends of lugs lt and the'side 13 to operative position upon the pulley wheel. The pulleys 18 are secured to the window frame by means of fastening members inserted through the perforations 18 which are provided on oppositesides of the pulley wheel'13 through the side 13.of the pulley. Said pulley cords15 are attached at 16at one end thereof to hangers 4:,the other ends of said cords being brought up over the pulleys and down upon one side of the window frame with suflicient slack 00rd to be secured to a clip 17 whereby the shade is held in place at any point within the guides 2.

The utility, adaptability, and advantages of my' improved form of vertically-adjustable shade hanger being obviously apparent, itis unnecessary to-further enlarge upon the same herein. I

Having now described and pointed out the new and useful features of'my invention, I do not limit myself to the shape of certain parts Where the shape is not essential, nor do I restrict myself to the eXact details of construction shown and described,but mean and intend to claim all equivalents and variations thereof not departing in principle from my invention and falling within the purview of the appended claims.
